摘要

我们提出VeRA，一个在浏览器即时(JIT)编译器中验证范围分析通过的系统。浏览器开发人员用c++的子集编写范围分析例程，验证开发人员编写基础结构来验证自定义分析属性。然后，VeRA自动验证范围分析例程，浏览器开发人员可以将其直接集成到JIT中。我们使用VeRA来翻译和验证Firefox的范围分析例程，它检测到一个新的，已经在浏览器中存在了六年的确认错误。

Towards a verified range analysis for JavaScript JITs

We present VeRA, a system for verifying the range analysis pass in browser just-in-time (JIT) compilers. Browser developers write range analysis routines in a subset of C++, and verification developers write infrastructure to verify custom analysis properties. Then, VeRA automatically verifies the range analysis routines, which browser developers can integrate directly into the JIT. We use VeRA to translate and verify Firefox range analysis routines, and it detects a new, confirmed bug that has existed in the browser for six years.
